BACKGROUND OF THE PRESENT INVENTION Field of Invention

The present invention relates to electric switches, and more particularly to a passive rebound switch, which is able to be installed into a wall surface and selectively alter different number of buttons.

Description of Related Arts

Generally, a standard wall switch has a significant advantage of installing into a wall surface easily. The standard wall switch refers to a wall-mounted push button switch that meets the national building standards or electrical product standards. For example, a length and a width of the switch are 86 mm for European standard, and a length and a width of the switch are 120 mm and 70 mm respectively for Japanese standard. There are also different walls switches for home and office use, such as in American standard. The common ground for these wall switches is easy to use regardless of age, such that the wall switches have been widely used in buildings all over the world. However, installing the conventional wall switch requires a pre-wiring system, wherein the wall switch is electrically connected to a power grid and an electric appliance, such as an electric lamp. Accordingly, the labor cost is relatively high and the labor time is relatively long for installing the wiring system behind the wall surface. In some cases, it is difficult to install the wiring system behind the hard surface, such as a tempered glass surface. Furthermore, it is dangerous to install the wiring system in the buildings, especially long wires may cause fire or other accidents related to electrical problems. The conventional wall switches cannot be used in wet or humid places such as bathrooms. In other words, there are lots of unsafe factors for the conventional wall switches.

The existing passive wireless switches or powerless wireless switches are expensive even though the switches are able to control some smart appliances. Due to the complexity of the mechanical design of the passive wireless switches, the cost thereof is relatively high, the reliability thereof is not high, and the practical application thereof is limited. Unlike the conventional wall switch to provide multiple button configurations (for example, four button configuration), the number of buttons per switch is limited for the passive wireless switch. Accordingly, the existing rebound type passive wireless switch can only configure to have 2 buttons, such that it is difficult to control multiple electric appliances, such as multiple light appliances, in the building, unless multiple switches are installed. However, increasing the number of switches will increase the cost. The operation mode and actuation pressing force of the existing passive wireless switches are quite different from those of the traditional rebound type wall switches. For example, the actuation pressing force of the existing passive wireless switches is larger than that of the traditional rebound type wall switches. Therefore, whether it is economical or practical view, the existing passive wireless switches cannot reach the level of traditional switches. Therefore, the existing passive wireless switches are need to improve and are not popular to be used in the buildings.

In addition, whether it is the existing passive wireless switches or the traditional rebound type wall switches, the number of buttons is preset at the production and cannot be changed thereafter. In other words, the manufactures must build different molds and/or additional steps in the manufacturing process for manufacturing the switch with different buttons, so as to increase the material and manufacturing cost of the switch. On the other hand, the merchants also need to determine the demand for different number of button switches according to the market research, and the consumers must also consider the need of the switch with different numbers of buttons. In fact, it is always a difference between the estimated quantity and the actual demand for the switch so as to cause the waste of material and labor cost.

Referring to FIGS. 1 to 9 of the drawings, a passive rebound switch, i.e. a powerless rebound switch, according to a preferred embodiment of the present invention is illustrated, wherein the passive rebound switch is adapted to selectively alter a number of button, and is configured to mount on a wall surface as an example. The passive rebound switch comprises a power generation module 50, an energy collecting module 58, a signal transmission module 20, a cover assembly 10, a plurality of detection controls 40 (such as three), and a housing 12.

The cover assembly 10 comprises a plurality of actuation buttons or detachable buttons 11 aligned side-by-side. In one embodiment, the cover assembly 10 is constructed to have three actuation buttons 11, wherein each of the actuation buttons 11 is configured as a cover panel to form a portion of top casing of the passive rebound switch. In other words, the actuation buttons 11 are placed side-by-side to form the top casing of the passive rebound switch. The housing 12 forms a bottom casing of the passive rebound switch. Accordingly, the above mentioned components are received in a receiving chamber as a resilient cavity formed between the actuation buttons 11 and the housing 12. According to the preferred embodiment, the receiving chamber is formed between the three actuation buttons 11 and the housing 12. The power generation module 50, the energy collecting module 58, the signal transmission module 20, and the detection controls 40 are received in the receiving chamber. When each of the actuation buttons 11 is subjected to an external force, such as a pressing force applied by an operator's hand, one side of each of the actuation buttons 11 can be driven to move in an up-and-down reciprocating movement.

On one hand, when one of the actuation buttons 11 is moved or pressed, the other adjacent actuation button 11 is stationary supported by its corresponding buffering element 39 at the idle position when no external is applied. As a result, only the actuation button 11 being pressed will be moved while the rest of the actuation buttons 11 will remain stationary. On the other hand, the buffering element 39 is made an elastic material to provide a buffering function, wherein when the detection control presser 114 of the actuation button 11 is driven to press on the buffering element 39 to electrify an I/O port, the buffering element 39 provides the elastic buffering force for protecting the detecting switch 40 from being damaged by an excessive pressure of the actuation button 11.

The power generation module 50 is retained in the power generation module retention slot 500.

The energy collecting module 58 serves a supporting frame retained between power generation module 50 and the interior casing assembly 30. A paddling member 57 is coupled to the power generation module 50, wherein the paddling element 57 is driven to move by the energy collecting module 58. When the external force is applied to the actuation button 11, the external force is transmitted to the auxiliary contact terminal 59 through the energy collecting module presser 115. Then, the auxiliary contact terminal 59 is actuated to press against the energy collecting module 58, wherein the energy collecting module 58 is pressed against the paddling member 57 to activate the power generation module 50 for converting the mechanical energy into the electrical energy. The power generation module 50 is connected to a power generation module terminal 56, and is electrically connected to the signal transmission module 20 through the power generation module terminal 56 to supply the electrical energy and the like to the electronic components such as the signal transmission module 20. It will be understood that the specific structure of the power generation module 50 of the present invention and its alternatives and power generation principle have been disclosed in detail in other patent documents by the inventor of the present invention, which can be applied to the power generation module 50 of the present invention.

The power generation module 50 further comprises a restoring element 55, such as a torsion spring, coupled at the housing 12 to move the actuation button 11 back from the actuated position to the idle position. Particularly, the restoring element 55 is coupled to the power generation module side panel 501 to reset the movement of the paddling member 57 via an elastic force of the restoring element 55 so as to restore the paddling element 57 back to its original position. When the paddling member 57 is reset, the auxiliary contact terminal 59, the interior casing assembly 30, and the actuation button 11 are driven to reset to their original positions via the paddling member 57, such that the actuation button 11 is rebounded and returned back to its original position.

Furthermore, the energy collecting module 58, generally having a U-shaped configuration, further comprises a main pressing portion 581, two side wing portions 582, a forcing arm 583, a pressing protrusion portion 584, and an arm slot 580. The two side wing portions 582 are integrally and perpendicularly extended from two ends of the main pressing portion 581 to form a U-shaped supporting member. In other words, one end of each of the side wing portions 582 is integrally extended from the main pressing portion 581 and another opposed end of each of the side wing portions 582 is bent downwardly to form the forcing arm 583. In other words, a portion of each of the side wing portions 582 is bent to integrally form with the forcing arm 583, wherein the forcing arm 583 is perpendicularly extended from the side wing portion 582. The pressing protrusion portion 584 is defined at an inner mid-portion of the main pressing portion 581, wherein the pressing protrusion portion 584 is integrally protruded from an inner edge of the main pressing portion 581 for actuating the power generation module. The arm slot 580 is formed within the main pressing portion 581 and the two side wing portions 582, such that the inner edges of the main pressing portion 581 and the two side wing portions 582 form a boundary of the arm slot 580. The power generation module 50 is disposed in the arm slot 580. When the external force is applied to the actuation button 11, the auxiliary contact terminal 59 is pressed by the energy collecting module presser 115. Then, the auxiliary contact terminal 59 is arranged to press against the main pressing portion 581 of the energy collecting module 58. The main pressing portion 581 is pivotally moved with respect to the forcing arm 583 as a pivot point. Then, the pressing protrusion portion 584 is moved by the pivotal movement of the main pressing portion 581 to press against the paddling member 57. Therefore, the power generation module 50 is driven and actuated by the paddling member 57 to convert the mechanical energy into the electrical energy.

It is worth mentioning that the main pressing portion 581 of the energy collecting module 58 preferably has a flat configuration, such as a flat plate, wherein it can be selectively adjusted or modified its size and shape according to actual needs. More than one actuation button 11 can be incorporated with the energy collecting module presser 115 to individually or concurrently press against the corresponding auxiliary contact terminals 59. Furthermore, each of the auxiliary contact terminals 59 can press the main pressing portion 581 of the energy collecting module 58 separately or simultaneously in order to press the paddling member 57 by the main pressing portion 581 of the energy collecting module 58 so as to actuate the power generation module 50 for generating the electrical energy. In other words, the passive rebound switch of the present invention requires one single power generating assembly for supplying the electrical energy to different actuation buttons 11 while being cost effective. At the same time, since only one single power generating assembly is utilized, the size and cost of the passive rebound switch of the present invention can be highly reduced. Thus, when using a stronger power generating assembly, the power generation capacity will be increased while being cost effective to incorporate with different power consumption requirement of the circuits.

Furthermore, the signal transmission module 20 comprises an energy integrated circuit configured to combine two consequent electrical energies together in response to the actuation button 11 being pressed and restored. In other words, the first electrical energy is generated when the actuation button 11 is pressed and the second electrical energy is generated when the actuation button 11 is restored back to its original position. Therefore, the power generation module 50 can be fully utilized to increase the overall power output, such that a command circuit of the signal transmission module 20 can effectively transmit the wireless signal at a higher radio frequency power and the control thereof is more reliable. In other words, the signal transmission module 20 of the present invention can serve as an energy synthesizer, such that the present invention is able to generate a larger power output comparing with the conventional expensive communication integrated circuit with low-power efficiency. The use of general inexpensive, high-power communication circuits, including single triode of wireless communication circuits, can be driven normally, so as to reduce the manufacturing costs and operating costs.

Furthermore, the arrangement of the actuation buttons 11 of the present invention can be formed with a cloth covered key 10. The waterproof chamber between the interior casing assembly 30 and the housing 12 is defined within a housing cavity within the cloth covered key 10 and the housing 12. When the actuation buttons 11 of the cloth covered key 10 are actuated separately or simultaneously, the interior casing assembly 30 can be actuated or pressed in the housing cavity formed between the cloth covered key 10 and the housing 12. The interior casing assembly 30 is arranged to press against the energy collecting module 58 housed in the waterproof chamber formed between the interior casing assembly 30 and the housing 12. The energy collecting module 58 is arranged to press the paddling member 57, such that the paddling element 57 is arranged to drive and actuate the power generation module 50. The power generation module 50 is arranged to convert the mechanical energy into the electrical energy in order to provide the electrical energy to the signal transmission module 20. The restoring element 55 is arranged to reset the power generation module 50 and the paddling member 57 back to their original positions. The power generation module 50 is arranged to convert the mechanical energy into the electrical energy again in response to the resetting of the power generation module 50. The resetting of the paddling member 57 is arranged to reset the energy collecting module 58 and the interior casing assembly 30 back to their original positions, such that the actuated actuation button 11 of the cloth covered key 10 is rebound and reset.

The energy collecting module presser 115 and the detection control presser 114 of the actuation button 11 can be defined as a button pressing portion 110 of the actuation button 11. The actuation button 11 further comprises a pressing extension rib 116 formed at the button pressing portion 110 at the bottom surface of the actuation button 11 for enhancing a strength of the actuation button 11. According to the preferred embodiment, the energy collecting module presser 115 and the detection control presser 114 are protruded, preferably integrally extended, from the pressing extension rib 116.

According to the preferred embodiment as an example, the passive rebound switch is constructed to have one power generation module 50 and three actuation buttons 11, wherein the three actuation buttons 11 form the cloth covered key 10. The three actuation buttons 11 provide three corresponding button pressing portions 110 respectively. Three button pressing portions 110 correspond to three buffer elements 39, three auxiliary contact terminals 59, and three detecting controls 40 respectively in order to ensure the interior casing assembly 30 able to be actuated by any one of the actuation buttons 11 of the cloth covered key 10 to actuate the power generation module 50 and to activate the signal transmission module 20. The detection control 40 is configured to pre-electrify the I/O port of the encoder of the signal transmission module 20, i.e. the signal transmission module 20 is pre-activated by the detection control 40, before the electrical energy is generated by the power generation module 50, so as to communicatively connect with the encoding control command. The signal transmission module 20 is configured for transmitting at least one control signal after the signal transmission module 20 is powered. Since the multiple buttons will not provide a relatively large affect for the circuit, the requirements thereof are not high. In addition, the manufacturing cost of the detecting control 40 is relatively low, and only one power generation module 50 is required. Unlike the conventional switch, the number of the detection controls 40 and one or more of the actuation buttons 11 can be selectively matched according to the passive rebound switch of the present invention. Therefore, the cost of the present invention will not be increased due to the number of the actuation buttons 11 and the detection controls 40.

The passive rebound switch of the present invention is able to selectively change the number of button for the cloth covered key 10 in order to enhance the practical use of the switch. Moreover, the actuation buttons 11 of the cloth covered key 10 can be selectively interchanged to fit the actual need of the switch. For example, the passive rebound switch provides a single button configuration as shown in FIGS. 10 to 11, the passive rebound switch provides a double button configuration as shown in FIGS. 12 to 13, and the passive rebound switch provides a triple button configuration as shown in FIGS. 14 to 15.

The user is able to configure a desired number of the actuation buttons 11 of the cloth covered key 10 as needed to achieve the required number of connection channels, so as to improve the practical use and the aesthetics appearance of the switch comparing to the conventional switch. The cloth covered key 10 of the present invention can also serve as a replaceable button cover. In order to dissemble each of the actuation buttons 11, the button pivot shaft 1130 of the actuation button 11 of the cloth covered key 10 can be disengaged with the pivot shaft slot 1230 of the housing 12, such that the actuation buttons 11 can be detached and rearranged their positions. Furthermore, since the cloth covered key 10 can be implemented as a replaceable key cover, the user is able to adjust and/or replace each of the actuation buttons 11. When the passive rebound switch of the present invention is installed on the wall surface, the passive rebound switch provides an aesthetic and decorative appearance for the wall with different colors and styles according to the different ages and user preferences as a part of the interior design.
